Other mistake: At the end of the intro, before the logo appears you can see Mojo Jojo's brain. His brain is green and it should be pink.
Other mistake: During the first dozen or so episodes, during the opening credits, Onizuka is shown spray-painting a picture of a woman on a wall, with the words "Love" and "Piece" written next to her. Obviously, "piece" is a mistranslation, and the wrong spelling. The correct text should read "Love" and "PEACE."
The Origin of the Silver Surfer: Part 3 - S1-E3
Other mistake: When the Navy is attacking the Silver Surfer, the shot of their fighter jets tailing him is suddenly shown to be the newsfeed on a TV. Even if the jets were filming their attack, they wouldn't be live broadcasting it for everyone to see.
Other mistake: When the monk returns the water bottle to Siro and Taja, not long after talking to them (not realising the water bottle belongs to Kung Lao), how did Siro and Taja get so far ahead of the monk in that short amount of time? (00:05:35 - 00:06:35)
Other mistake: They keep saying the taxi cab is 20 years old, but that cab is brand-new in the episode.
